New preprint out of the lab natural variation in pollen heat susceptibility in Mimulus. Key finding: An restricted alpine endemic species, Mimulus tilingii, has universally high pollen susceptibility, while the widespread M. guttatus is much more variable. www.biorxiv.org/content/10.6...
Heat stress reveals divergent pollen viability responses across species and populations of monkeyflower
Premise Rising temperatures can reduce plant reproductive success by disrupting pollen development, yet little is known about how reproductive heat sensitivity varies among natural populations. We eva...
